From the angle of engineering application, this article analysed the corrosion characteristics and damage causes of the current structural used concrete in the region of Hangzhou gulf, on the basis of on-site survey of all the Marine concrete projects in that area. Taking HPC used in Marine as research objective, this article put great emphasis on the influence of the composition cementing material system to concrete performance, and make a preliminary probe into the action mechanism of the composite effects of various mineral materials in improving the performance of concrete by laser measuring size machine and EMPA. Through experiments, the article discussed how chloride ingression in concrete will be effected by such factors as exposure time, chloride binding, environment temperature, stress and cracks conditions; and also analysed the symptoms of these factors in the model of concrete service life prediction by conference to all related research reports both home and aboard. On the foundation of abovementioned research, this paper brought up an engineering model of service life prediction of marine concrete, which is based on chloride-induced corrosion.
